Email body Missing

Hello Experts,

I am facing issue while sending mail from Data Services . Have configured SMTP details in Job Server, my DS server is running on Linux platform.

Using the below command to trigger mail from DS Designer.

smtp_to( 'abc@gmail.com', 'Hello World','This is Body',10,10);

But am receiving the mail with only subject , body is missing.

We have tested the same SMTP server through telnet passing subject and body , its working fine.

Please help me in this , is there any other config missing?

Regards,

Aisurya
